NGC 7072 is an intermediate spiral galaxy located about 210 million light-years away in the constellation of Grus.[2][3] NGC 7072 was discovered by astronomer John Herschel on September 5, 1834.[4]
NGC 7072 is a member of the NGC 7060 group, a group of galaxies which contains six members, including NGC 7057, NGC 7060, NGC 7072, NGC 7072A, ESO 287-16, and ESO 287-26.[5] However, according to A.M. Garcia, the galaxy is in the IC 5105 group (also known as LGG 445), which contains 19 members, including NGC 7057, NGC 7087, NGC 7060, NGC 7072, NGC 7075, NGC 7110, NGC 7130, plus four galaxies from the Index Catalogue and eight galaxies from the ESO catalog.[6]
One supernova has been observed in NGC 7072: SN 2024yok (type IIb, mag. 18.35).[7]
